What he does: The record-setting sharpshooter traveled to a refugee camp in western Tanzania over the summer as part of the Nothing But Nets charity campaign. Curry donated three insecticide-treated mosquito nets for every 3-pointer he made last season, when he made more 3-pointers than anyone in NBA history (272). The nets prevent the spread of malaria. This year Curry doubled his donation to six bed nets for every 3-pointer made and the Warriors pledge to match that donation.

In his words: "I picked nets because it's a way people can make a huge difference right away. We can really save kids' lives. I've seen it now. I'll never forget it." (via ESPN.com).

What he does: The goalkeeper will donate almost $18,000 to the Navy SEAL Foundation next week as part of his rapidly growing "Saves for SEALs" program. Busch pledged $50 for each save he made during the 2013 season and the Earthquakes matched the donation. Charity auctions -- such as selling his game-used gear -- helped him more than double the $8,100 donation he made a year ago.

What he does: The veteran left-hander is a prominent member of Not For Sale's Free2Play campaign, an organization that assists young adults who are trying to readjust to the world after being freed from human trafficking and slavery. Affeldt pledges a $100 donation for every strikeout and has recruited other athletes to support the cause, such as Matt Cain and Matt Holliday.

In his words: "We've all been given a gift. And what we do with that gift, what we do with that talent, to bring around positive change in the world is what's going to make you feel successful." (via mlb.com)

What he does: As an advisory board member of the You Can Play Project, the forward strives to help the organization achieve its goal of "ensuring quality, respect and safety for all athletes, without regard to sexual orientation." Teammates voted Wingels as the Sharks nominee for the NHL's King Clancy Memorial Trophy, which goes to the player who best represents the humanitarian spirit.

In his words: "For kids who are seeing these (You Can Play) videos, that's important. You see your favorite NHL player or your favorite MLB player speaking up about it, and you want to be like them." (via BANG newspapers)

What he does: The left-hander's many causes include the Freedom Alliance, an educational and charitable organization that supports and honors our military service members and their families. He has visited and supported veterans at the VA Hospital in Palo Alto and the Walter Reed Hospital in Washington, D.C. He also has donated numerous signed items for Memorial Day and Fourth of July silent auctions, which led to a $5,000 donation to Freedom Alliance.

In his words: "These men and women sacrifice so much for our country and community, and it is the least we could do to express our gratitude. As a proud member of a military family, I know firsthand the dedication it takes." (via Oakland Athletics)

What he does: His youth foundation aims to help at-risk kids to get on the right track, socially and academically. The initiatives range from 30-minute chats with guest speakers to college tours, workshops and scholarship opportunities.

What he said: "A lot of kids, when I go back home, they're not getting into anything. They're just chilling on the corner. And I'm like, 'Y'all are not doing anything, so how about an after-school program we could set up?''' (via Gazette.net)
